during the glue spreading process was fully reacted in comparison to other processes of synthesis 1391. A similar study reported that low condensation PF resins co-reacted under alka- line conditions with up to 42% molar urea on phenol during resin preparation were found to yield PUF resins capable of faster hardening times than equivalent pure PF resins prepared under identical conditions l19l Once heat is introduced, a shorter hot pressing time might be sufficient to cure the resin and a low gas formaldehyde emission Elaeis palm plywood panel is expected to be obtained, because the 13 NMR results indicated there is no formaldehyde gas emitted and excessive urea in the resin system. Therefore, it can be shown that a reduction in the hot pressing time from 18 min to 16 min can be achieved without harming the total performance of the treated Elaeis palm plywood panel as indicated in Table 1
